Current HVAC tech here, I had Danny come out and did a performance evaluation on my home. Working in the HVAC industry I have a decent knowledge base on air flow and humidity in the home. After Danny came over he asked questions like : if there were any concerns & what I was looking to improve.
My main concern was air intrusion and if my A/C was fighting my home cause being in the HVAC trade I know my A/C is running correctly. He measure the air intrusion with a blower door test, s arched for air leaks with a smoke wand, and after showing where the air came from with the smoke put a thermal camera to show the heat coming in through those spots. Learned a lot from talking to the gentleman and everything he said lined up with what I know from the A/C side.
Air & duct sealing, measured not guessed.
The biggest leaks in most homes are hidden in the ceiling, the attic floor and the ductwork. We find them, seal them properly, and show you the before and after numbers.
Your AC is cooling the attic too
Every gap in your ceiling lets cooled air escape and pulls hot, humid attic air back in: recessed lights, attic hatches, bath fans, wire and pipe holes, and the tops of interior walls.
Ducts are often the worst offender. ENERGY STAR estimates a typical duct system loses 20 to 30% of the air moving through it to leaks, holes and poor connections. In a Florida attic, that's cooled air you paid for, blowing into a 130°F space.
- Find the leaks you can't see
- Seal them with the right material for each gap
- Prove it with a before and after number
What sealing actually does for you
Air sealing is one of the best-value upgrades for a Florida home. Here's why.
Cooler back rooms
Rooms at the end of long duct runs finally get the air they're supposed to, and the whole house evens out.
Lower energy bills
Less cooled air lost to the attic means shorter AC run times. One customer's bill dropped by over $100 after sealing.
Less dust indoors
Fewer leaks pulling attic dust, insulation fibers and debris into your rooms and onto your furniture.
Less humidity
Humid attic air stays in the attic instead of your living room, so the house feels less sticky.
Fewer pests
Sealed gaps and penetrations mean fewer highways for insects and other critters.
Proof, not promises
A measured leakage number before and after, so you can see exactly what changed.
Is your home leaking air?
Tap the ones you've noticed. Two or more usually means there's money leaking out of your ceiling.
Air & duct sealing, step by step
Usually done in a day, or as part of a bigger insulation job.
- 1
Free inspection
We look at your attic, ductwork and air handler, take photos, and talk through the problems you've noticed in the house.
- 2
Baseline test
A blower door is fitted into an exterior doorway and gently depressurizes the house, giving us a starting leakage number.
- 3
Find the leaks
With the fan running, leaks show themselves. We track them down with a smoke pencil and a thermal camera, room by room and in the attic.
- 4
Seal the house
Foam, caulk and sealants on recessed lights, top plates, plumbing and wiring holes, chases and the attic hatch.
- 5
Seal the ducts
Accessible duct joints, boots and connections are sealed with mastic so the air you pay for reaches your rooms.
- 6
Re-test
We run the blower door again, watch the number drop, and record the before and after result for you.
- 7
Walk-through
We show you photos of what we sealed, explain the results and clean up before we leave.
Every leak we seal starts with an inspectionWhy we test instead of guess
Plenty of companies will caulk a few gaps. Here's the difference a measured approach makes.
| Typical approach | Heat Hunters air & duct sealing | |
|---|---|---|
| Finding leaks | ✕A quick look around the attic | ✓Blower door, smoke pencil and thermal camera |
| Ductwork | ✕Often ignored, or taped | ✓Joints, boots and connections sealed with mastic |
| Hidden leaks | ✕Covered by insulation and missed | ✓Found and sealed before insulation goes down |
| Proof | ✕"It should be better" | ✓Before and after leakage numbers |
| The answer to hot rooms | ✕A bigger AC unit | ✓Fix where the cool air is going first |
| Long-term result | ✕Hit or miss | ✓Measurably tighter home |

What customers say about sealing
Check this out anyone looking to lower their electric bills from the loss of air conditioning and heating. I called a few companies that came in and showed me a different way to solve my problems and then I met Danny from heat Hunters Incorporated. Danny the owner did a blower test and showed me how air was leaking out all over the place I was amazed. They had a smoke machine thingy also where you could actually see where the leaks were. The last thing he checked was my attic which was unbelievably hot and he tested to show where all the problems were. Danny was very knowledgeable and professional 100%. I signed to deal with him and can't wait till my install next week. I know the job is going to be way more sufficient than the typical spray-in foam type of material that some use.
At first I wasn't sure what to expect with this company. After having everything in my attic sealed up air tight it lowered my electric bill by over $100. Would recommend them to everybody who owns a home!
My wife and I have had pretty bad allergies since moving into this house in Florida. We met Danny at a trade show and he told us it might be because of dirty attic air coming into our living area. I was skeptical but had him over to check for air leaks and inspect the attic.
I was genuinely shocked at all the leaks he found and how nasty the attic was. I had no idea all my can lights in the ceiling were leaking so much. We had them do a full attic restoration and they got rid of all the old nasty insulation, disinfected, sealed up our ducts, and sealed up the attic floor before adding new insulation. They even installed some metal mesh around the house so rodents wont get in.
Believe it or not our allergies are not acting up at all anymore! I'm excited to see how much lower this next electric bill is too. Very happy. Thanks guys
I had a great experience with Heat Hunters. Their inspection was thorough, professional and easy to understand. They identified several areas where my home was losing energy that I never would have noticed on my own. The thermal imaging technology clearly showed where insulation improvements and air leaks were affecting efficiency.
Mr. Daniel Dalziel was very knowledgeable, friendly and took the time to explain the findings and recommendations without any pressure.
I highly recommend Heat hunters to any homeowner looking to identify energy loss and make smarter improvements to their home.
Amazing job by the team at Heat Hunters! My house is so much cooler and efficient. My AC no longer runs non stop!
